4.    Earnings Per Share

We had 23,670 shares of nonvested restricted stock at June 30, 2017 and 25,255 shares of nonvested restricted stock at June 30, 2016 that were excluded from the calculation of diluted earnings per share, as their effect on earnings per share would be anti-dilutive.

The nonvested restricted stock is considered a participating security since the restricted stock contains nonforfeitable rights to dividends. As such, we use the two-class method to compute basic and diluted earnings per share for all periods presented since this method yielded a more dilutive result than the treasury-stock method. The following table illustrates the earnings allocation method utilized in the calculation of basic and diluted earnings per share.

	Second Quarter Ended June 30,				Six Months Ended June 30,
(in thousands, except per-share amounts)	2017		2016		2017		2016
Earnings per share numerator:
Net income attributable to common shareholders before allocation of earnings to participating securities	$	62,728	$	64,389	$	126,665	$	126,320
Earnings allocated to participating securities	125		134		252		265
Net income attributable to common shareholders after allocation of earnings to participating securities	$	62,603	$	64,255	$	126,413	$	126,055
Earnings per share denominator:
Weighted-average number of shares of common stock outstanding - basic and diluted	11,829		11,823		11,829		11,831
Earnings per share - basic and diluted	$	5.29	$	5.43	$	10.69	$	10.65

5.    Intangibles (Net of Amortization) and Goodwill

The net carrying amount of intangibles and goodwill was $10 million at June 30, 2017 and December 31, 2016. The gross carrying amount and accumulated amortization of each type of intangible asset and goodwill are presented in the table below.

	June 30, 2017				December 31, 2016
(in thousands)	Gross Carrying Amount		Accumulated Amortization		Gross Carrying Amount		Accumulated Amortization
Amortizing intangible assets
Formulas and technology	$	2,719	$	2,074	$	2,678	$	1,958
Contracts	2,000		100		2,000		0
Customer bases	6,953		4,110		6,938		3,961
Trademarks and trade names	1,525		1,140		1,513		1,069
Goodwill	4,444				4,295
	$	17,641	$	7,424	$	17,424	$	6,988

All of the intangibles relate to the petroleum additives segment. The change in the gross carrying amount between December 31, 2016 and June 30, 2017 is due to foreign currency fluctuations. There is no accumulated goodwill impairment.

Amortization expense was (in thousands):

Second quarter ended June 30, 2017	$	218
Six months ended June 30, 2017	436
Second quarter ended June 30, 2016	301

Estimated amortization expense for the remainder of 2017, as well as estimated annual amortization expense related to our intangible assets for the next five years, is expected to be (in thousands):

2017	$	428
2018	834
2019	813
2020	504
2021	440
2022	440

We amortize contracts over 10 years; customer bases over 20 years; formulas and technology over 10 years; and trademarks and trade names over 10 years.

6.    Long-term Debt

(in thousands)	June 30, 2017		December 31, 2016
Senior notes - 4.10% due 2022 (net of related deferred financing costs)	$	346,798	$	346,505

Revolving credit facility	26,426		156,000

	$	627,976	$	507,275

The outstanding 4.10% senior notes have an aggregate principal amount of $350 million and are registered under the Securities Act of 1933, as amended (Securities Act).

On January 4, 2017, we issued $250 million in senior unsecured notes in a private placement with The Prudential Insurance Company of America and certain other purchasers. These notes bear interest at 3.78% and mature on January 4, 2029. Interest is payable semiannually and principal payments of $50 million are payable annually beginning on January 4, 2025. We have the right to make optional prepayments on the notes at any time, subject to certain limitations. The note purchase agreement contains representations, warranties, terms and conditions customary for transactions of this type. These include negative covenants, certain financial covenants, and events of default which are substantially similar to the covenants and events of default in our revolving credit facility. The proceeds from the 3.78% senior notes were used in part to pay off the outstanding amount on our revolving credit facility.

The capital lease obligation in the table above is related to the Singapore manufacturing facility.

The following table provides information related to the unused portion of our revolving credit facility:

(in thousands)	June 30, 2017		December 31, 2016
Maximum borrowing capacity under the revolving credit facility	$	650,000	$	650,000
Outstanding borrowings under the revolving credit facility	26,426		156,000
Outstanding letters of credit	3,535		3,483
Unused portion of revolving credit facility	$	620,039	$	490,517

The average interest rate for borrowings under our revolving credit facility was 2.0% during the first six months of 2017 and 1.9% during the full year of 2016.

We were in compliance with all covenants under our debt agreements at June 30, 2017 and at December 31, 2016, as applicable.

7.    Commitments and Contingencies

Legal Matters

We are involved in legal proceedings that are incidental to our business and may include administrative or judicial actions. Some of these legal proceedings involve governmental authorities and relate to environmental matters. For further information, see Environmental below.

While it is not possible to predict or determine with certainty the outcome of any legal proceeding, we believe the outcome of any of these proceedings, or all of them combined, will not result in a material adverse effect on our consolidated results of operations, financial condition, or cash flows.

In late 2013, Afton Chemical Corporation (Afton) initiated a voluntary self-audit of its compliance with certain sections of the Toxic Substances Control Act (TSCA) under the Environmental Protection Agency's (EPA) audit policy (Audit Policy). If any potential TSCA violations are discovered during the audit, we would voluntarily disclose them to the EPA under the Audit Policy. In August 2014, the EPA staff began its own TSCA inspection of both Afton and Ethyl. While it is not possible to predict or determine with certainty the outcome, we do not believe that any findings identified as a result of our audit or the EPA’s TSCA inspection will have a material adverse effect on our consolidated results of operations, financial condition, or cash flows.

Environmental

We are involved in environmental proceedings and potential proceedings relating to soil and groundwater contamination, disposal of hazardous waste, and other environmental matters at several of our current or former facilities, or at third-party sites where we have been designated as a potentially responsible party (PRP). While we believe we are currently adequately accrued for known environmental issues, it is possible that unexpected future costs could have a significant impact on our financial position, results of operations, and cash flows. Our total accruals for environmental remediation, dismantling, and decontamination were approximately $15 million at June 30, 2017 and $16 million at December 31, 2016. Of the total accrual, the current portion is included in accrued expenses and the noncurrent portion is included in other noncurrent liabilities on the Condensed Consolidated Balance Sheets.

Our more significant environmental sites include a former TEL plant site in Louisiana (the Louisiana site) and a Houston, Texas plant site (the Texas site). Together, the amounts accrued on a discounted basis related to these sites represented approximately $9 million of the total accrual above at June 30, 2017 and $10 million of the total accrual above at December 31, 2016, using discount rates ranging from 4% to 9% for both periods. The aggregate undiscounted amount for these sites was $12 million at June 30, 2017 and $13 million at December 31, 2016. Of the total accrued for these two sites, the amount related to remediation of groundwater and soil for the Louisiana site was $4 million at both June 30, 2017 and December 31, 2016. The amount related to remediation of groundwater and soil for the Texas site was $5 million at both June 30, 2017 and December 31, 2016.

In 2000, the EPA named us as a PRP under Superfund law for the clean-up of soil and groundwater contamination at the five grouped disposal sites known as "Sauget Area 2 Sites" in Sauget, Illinois. Without admitting any fact, responsibility, fault, or liability in connection with this site, we are participating with other PRPs in site investigations and feasibility studies. In December 2013, the EPA issued its Record of Decision confirming its remedies for the selected Sauget Area 2 Sites. We have accrued our estimated proportional share of the remedial costs and expenses addressed in the Record of Decision. We do not believe there is any additional information available as a basis for revision of the liability that we have established at June 30, 2017. The amount accrued for this site is not material.

9.    Fair Value Measurements

The carrying amount in the Condensed Consolidated Balance Sheets and the fair value of cash and cash equivalents were $278 million at June 30, 2017 and $192 million at December 31, 2016. The fair value is categorized in Level 1 of the fair value hierarchy. No material events occurred during the six months ended June 30, 2017 requiring adjustment to the recognized balances of assets or liabilities which are recorded at fair value on a nonrecurring basis.

Long-term debt – We record the carrying amount of our long-term debt related to the 4.10% senior notes at historical cost, less deferred financing costs. We record the carrying amount of our long-term debt related to the 3.78% senior notes at historical cost. The estimated fair value of our long-term debt is shown in the table below and is based primarily on estimated current rates available to us for debt of the same remaining duration and adjusted for nonperformance risk and credit risk. The estimated fair value of our publicly-traded 4.10% senior notes included in long-term debt in the table below is also based on the last quoted price closest to June 30, 2017. The fair value of our debt instruments are categorized as Level 2.

	June 30, 2017				December 31, 2016
(in thousands)	Carrying Amount		Fair Value		Carrying Amount		Fair Value
Long-term debt (excluding capital lease obligation)	$	623,224	$	640,815	$	502,505	$	507,925

10.    Recent Accounting Pronouncements

Recently Issued Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (FASB) issued ASU No. 2014-09, “Revenue from Contracts with Customers (Topic 606)” (ASU 2014-09). ASU 2014-09 replaces the previous guidance and clarifies the principles for revenue recognition. It requires a five-step process for revenue recognition that represents the transfer of goods or services to customers in an amount that reflects the consideration expected to be received by a company. ASU 2014-09 also requires enhanced disclosures regarding the nature, amount, timing, and uncertainty of revenues and cash flows from contracts with customers. ASU 2014-09 is effective for our reporting period beginning January 1, 2018. Entities can transition to the standard either retrospectively or as a cumulative-effect adjustment as of the date of adoption. We currently anticipate adopting the standard as a cumulative-effect adjustment. We expect to continue the evaluation, analysis, and documentation of our adoption of ASU 2014-09 (including those subsequently issued updates that clarify the provisions), throughout most of this year as we work towards implementation and finalize the impact the adoption will have on our consolidated financial statements.

14

In February 2016, the FASB issued ASU No. 2016-02, "Leases (Topic 842)" (ASU 2016-02). The FASB issued ASU 2016-02 to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and requiring disclosures related to certain information about leasing arrangements. Under the new guidance, operating leases are, in most cases, required to be recognized on the balance sheet as a lease asset and liability. A modified retrospective approach is required for the adoption of ASU 2016-02, which is effective for our reporting period beginning January 1, 2019. Early adoption is permitted. We are currently assessing the impact that the adoption of ASU 2016-02 will have on our consolidated financial statements.

In March 2017, the FASB issued ASU No. 2017-07, "Compensation-Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost" (ASU 2017-07), which requires that an employer report the service cost component of net benefit cost in the same line item as other compensation costs arising from services rendered by the pertinent employees during the period. The other components of net benefit cost are required to be presented in the income statement outside of operating profit. ASU 2017-07 also allows only the service cost component to be eligible for capitalization in assets. There will be no change to net income as a result of ASU 2017-07, which is effective for our reporting period beginning January 1, 2018. Retrospective application is required for the income statement presentation and prospective application is required for the capitalization of the service cost component in assets. The adoption of ASU 2017-07 will result in a change within operating profit with a corresponding change in other income (expense), net to reflect the impact of presenting all components of net benefit cost, except for service cost, outside of operating income. See Note 3 for the components of our net benefit costs. We do not expect a material impact to our consolidated balance sheets or consolidated statements of cash flows.

11.    Subsequent Events

On July 3, 2017, Afton Chemical de Mexico, S.A. de C.V., an indirect, wholly-owned subsidiary of NewMarket Corporation, acquired approximately 99.5% of the outstanding capital stock of Aditivos Mexicanos, S.A. de C.V. (AMSA), a petroleum additives manufacturing, sales and distribution company based in Mexico City, Mexico.

We are performing a valuation of the acquired business, as well as finalizing the working capital statement and related final purchase price. We expect both to be completed during the third quarter of 2017, and we do not expect the purchase price to be significantly different from the $185 million cash paid.

Overview

When comparing the results of the petroleum additives segment for the first six months of 2017 with the first six months of 2016, net sales increased 6.1% primarily due to increased shipment volumes, partially offset by lower selling prices. Petroleum additives operating profit was 4.4% lower for the first six months of 2017 as compared to the first six months of 2016, but the operating profit margin remained strong at 17.9%.

Our operations generate cash that is in excess of the needs of the business. We continue to invest in and manage the business for the long-term with the goal of helping our customers succeed in their marketplaces. Our investments continue to be in organizational talent, technology development and processes, and global infrastructure, consisting of technical centers, production capability, and geographic expansion.

On July 3, 2017, we completed our acquisition of Aditivos Mexicanos S.A. de C.V., a petroleum additives manufacturing, sales and distribution company based in Mexico City, Mexico. The acquisition complements and expands our existing presence in the Latin America region, and also improves our supply capabilities to better serve our customers.

Results of Operations

Net Sales

Consolidated net sales for the second quarter of 2017 totaled $547.2 million, representing an increase of 4.9% from the second quarter of 2016 of $521.8 million. Consolidated net sales for the first six months of 2017 were $1.1 billion which was an increase of 5.7% from the first six months of 2016 of $1.0 billion. The following table shows net sales by segment and product line.

	Second Quarter Ended June 30,				Six Months Ended June 30,
(in millions)	2017		2016		2017		2016
Petroleum additives
Lubricant additives	$	453.4	$	432.2	$	897.3	$	851.0
Fuel additives	90.8		83.9		186.9		171.2
Total	544.2		516.1		1,084.2		1,022.2
All other	3.0		5.7		5.8		9.5
Net sales	$	547.2	$	521.8	$	1,090.0	$	1,031.7

Petroleum Additives Segment

The regions in which we operate include North America (the United States and Canada), Latin America (Mexico, Central America, and South America), Asia Pacific, and the Europe/Middle East/Africa/India (EMEAI) region. While there is some fluctuation, the percentage of net sales generated in the regions remained fairly consistent when comparing the first six months of 2017 with the same period in 2016, as well as with the full year in 2016.

Petroleum additives net sales for the second quarter of 2017 were $544.2 million compared to $516.1 million for the second quarter of 2016, an increase of 5.4%. The increase was predominantly in the Asia Pacific region, with a small increase in the EMEAI region. The North America and Latin America regions experienced small decreases during the second quarter of 2017 compared to the second quarter of 2016. Petroleum additives net sales for the first six months of 2017 were $1.1 billion compared to $1.0 billion for the first six months of 2016, an increase of 6.1%. Similar to the second quarter results, the increase between the 2017 and 2016 six month periods was predominantly in the Asia Pacific and EMEAI regions with small decreases in North America and Latin America.

The following table details the approximate components of the increase in petroleum additives net sales between the second quarter and first six months of 2017 and 2016.

(in millions)	Second Quarter			Six Months
Period ended June 30, 2016	$	516.1		$	1,022.2
Lubricant additives shipments	35.9			84.3
Fuel additives shipments	5.0			14.7
Selling prices	(8.2		)	(28.7		)
Foreign currency impact, net	(4.6		)	(8.3		)
Period ended June 30, 2017	$	544.2		$	1,084.2

When comparing both the second quarter periods and the six month periods, higher volumes shipped was the predominant factor resulting in the increase in petroleum additives net sales, with both unfavorable selling prices and foreign currency partially offsetting the favorable impact from shipments. The U.S. Dollar strengthened against most of the major currencies in which we transact, with most of the impact on net sales resulting from the change in the Euro and the Chinese Renminbi for both the second quarter and six month periods of 2017.

The volume of product shipments for petroleum additives on a worldwide basis increased approximately 6.4% when comparing the two second quarter periods and 10.1% when comparing the first six months of 2017 with the same period in 2016. For both the second quarter and six month comparative periods, shipments of both lubricant additives and fuel additives products increased. Lubricant additives product shipments for both the second quarter and six month comparative periods increased across all regions except for North America, which experienced small decreases when compared to levels in the second quarter and first six months of 2016. The increase in the volume of product shipments in fuel additives for the second quarter comparative periods was predominantly in the EMEAI region. The increase in fuel additives product shipments for the six

17

month comparative periods was also predominantly in the EMEAI region, with a small increase also in the North America region. The Latin America region experienced a small decrease during the six month comparative periods, while the Asia Pacific region was substantially unchanged when comparing the six month periods.

All Other

The “All other” category includes the operations of the TEL business and certain contracted manufacturing and services associated with Ethyl.

Segment Operating Profit

NewMarket evaluates the performance of the petroleum additives business based on segment operating profit. NewMarket Services Corporation expenses are charged to NewMarket and each subsidiary pursuant to services agreements between the companies. Depreciation on segment property, plant, and equipment, as well as amortization of segment intangible assets, is included in segment operating profit.

The following table reports segment operating profit for the second quarter and six months ended June 30, 2017 and June 30, 2016.

	Second Quarter Ended June 30,				Six Months Ended June 30,
(in millions)	2017		2016		2017		2016
Petroleum additives	$	94.9	$	102.5	$	194.0	$	202.9
All other	$	0.9	$	1.4	$	1.9	$	1.6

Petroleum Additives Segment

The petroleum additives segment operating profit decreased $7.6 million when comparing the second quarter of 2017 to the second quarter of 2016 and $8.9 million when comparing the first six months of 2017 to the same period in 2016. Both comparative periods included the impact of the same factors that affected gross profit (see discussion below) including a small favorable currency impact when comparing the second quarter of 2017 with the second quarter of 2016, but a small unfavorable impact when comparing the first six months of 2017 with the first six months of 2016. The operating profit margin was 17.4% for the second quarter of 2017 as compared to 19.9% for the second quarter of 2016 and was 17.9% for the first six months of 2017 as compared to 19.9% for the first six months of 2016. For the rolling four quarters ended June 30, 2017, the operating profit margin for petroleum additives was 17.9%, which is in line with our expectations for the performance of our business over the long-term. While operating profit margins will fluctuate from quarter to quarter due to multiple factors, we do not operate our business differently from quarter to quarter. We believe the fundamentals of our business and industry are unchanged. Our continued focus is on developing and delivering innovative, technology-driven solutions to our customers.

Petroleum additives gross profit decreased $13.2 million when comparing the two second quarter periods and $19.3 million when comparing the firstsix monthsof2017and2016. Cost of goods sold as a percentage of net sales was 69.9% for the second quarter of 2017, up from 65.7% for the second quarter of 2016 and 69.4% for the firstsix monthsof2017, up from 65.6% for the first six months of 2016.

When comparing both the second quarters and first six months of 2017 and 2016, the primary factors in the decrease in gross profit resulted from unfavorable raw material costs and selling prices, which contributed over 100% of the change. These unfavorable factors were partially offset by increases in product shipments (as discussed in the Net Sales section above), as well as a small improvement in conversion cost. The sales price variance for the comparative periods included the impact from foreign currency rate fluctuations as discussed in the Net Sales section above.

Petroleum additives selling, general, and administrative expenses (SG&A) for the second quarter of 2017 were $0.4 million, or 1.2% lower as compared to the second quarter of 2016, and $2.8 million, or 4.0%, lower for the first six months of 2017 as compared to the first six months of 2016. SG&A as a percentage of net sales was 6.1% for the second quarter of 2017, 6.5% for the second quarter of 2016, 6.1% for the first six months of 2017, and 6.7% for the first six months of 2016. Our SG&A costs are primarily personnel-related and include salaries, benefits, and other costs associated with our workforce. There were no significant changes in the drivers of these costs when comparing the periods.

18

Our investment in petroleum additives research, development, and testing (R&D) for the second quarter of 2017 decreased $5.1 million from the second quarter of 2016. The first six months of 2017 decreased $7.7 million from the first six months of 2016. The decrease for both comparative periods was reflected in both the lubricant additives and fuel additives product lines. As a percentage of net sales, R&D was 6.5% for the second quarter 2017, 7.9% for the second quarter 2016, 6.7% for the first six months of 2017, and 7.8% for the first six months of 2016. Our R&D investments reflect our efforts to support the development of solutions that meet our customers' needs, as well as new and evolving standards, and to support our expansion into new product areas. Our approach to R&D investment, as it is with SG&A, is one of purposeful spending on programs to support our current product base and to ensure that we develop products to support our customers' programs in the future. R&D investments include personnel-related costs, as well as internal and external testing of our products.

The following discussion references the Consolidated Financial Statements beginning on page 4 of this Quarterly Report on Form 10-Q.

Interest and Financing Expenses

Interest and financing expenses were $5.4 million for the second quarter of 2017, $4.0 million for the second quarter of 2016, $10.9 million for the first six months of 2017, and $8.1 million for the first six months of 2016. The increase in interest and financing expenses between both the second quarter and the six month periods of 2017 and 2016 resulted from a higher average interest rate, as well as higher average debt.

Other Income (Expense), Net

Other income (expense), net was income of $0.2 million for the second quarter of 2017, expense of $1.3 million for the second quarter of 2016, income of $0.4 million for the first six months of 2017, and expense of $3.5 million for the first six months of 2016. The amount for the two 2016 periods included the impact from a derivative instrument representing an interest rate swap recorded at fair value through earnings.

Income Tax Expense

Income tax expense was $22.6 million for the second quarter of 2017 and $27.7 million for the second quarter of 2016. The effective tax rate was 26.5% for the second quarter of 2017 and 30.1% for the second quarter of 2016. Income tax expense decreased $3.1 million due to the lower effective tax rate, while the decrease in income before income tax expense resulted in the remaining decrease in income tax expense.

Income tax expense was $46.9 million for the first six months of 2017 and $54.7 million for the first six months of 2016. The effective tax rate was 27.0% for the first six months of 2017 and 30.2% for the first six months of 2016. Income tax expense decreased $5.6 million due to the lower effective tax rate, with the remainder of the change due to lower income before income tax expense.

The effective tax rates for both the second quarter and six month comparative periods included the benefit of income in foreign jurisdictions with lower tax rates than the United States tax rate. During the 2017 periods, a higher percentage of our income before income taxes resulted from operations in foreign locations than during the 2016 periods.

Cash Flows, Financial Condition, and Liquidity

Cash and cash equivalents at June 30, 2017 were $278.0 million, which was an increase of $85.9 million since December 31, 2016.

Cash and cash equivalents held by our foreign subsidiaries amounted to $263.8 million at June 30, 2017 and $189.2 million at December 31, 2016. A significant amount, but not all, of these foreign cash balances are associated with earnings that we have asserted are indefinitely reinvested. We plan to use these indefinitely reinvested earnings to support growth outside of the United States through funding of operating expenses, capital expenditures, and other cash needs of our foreign subsidiaries. Periodically, we repatriate cash from our foreign subsidiaries to the United States through intercompany dividends. These intercompany dividends are paid only by subsidiaries whose earnings we have not asserted are indefinitely reinvested or whose earnings qualify as previously taxed income, as defined by the United States Internal Revenue Code. If circumstances were to change that would cause these indefinitely reinvested earnings to be repatriated, an incremental U.S. tax liability would be incurred. Dividends received from foreign subsidiaries during the six months ended June 30, 2017 and June 30, 2016 were not material. The amount of cash that we repatriate from foreign subsidiaries in any given year is dependent upon many factors including utilization of available cash in the foreign locations for working capital, capital investments, and other needs.

We expect that cash from operations, together with borrowing available under our revolving credit facility, will continue to be sufficient to cover our operating needs and planned capital expenditures for at least the next twelve months.

19

Cash Flows – Operating Activities

Cash flows provided from operating activities for the first six months of 2017 were $92.6 million, which included a decrease of $51.4 million from higher working capital requirements. The $51.4 million excluded a favorable foreign currency impact to the components of working capital on the balance sheet.

Other than the increase in cash and cash equivalents, the most significant changes in working capital resulted from an increase in accounts receivable and inventories along with a decrease in accrued expenses, which were partially offset by an increase in accounts payable. The higher accounts receivable balance was primarily due to higher sales levels in most regions when comparing the second quarter of 2017 with the fourth quarter of 2016. Most of the increase in inventory was in the EMEAI region and resulted from increase in demand, timing of shipments, and replenishment of certain raw materials from levels at the end of 2016. The increase in accounts payable was due to timing of payments, while the decrease in accrued expenses resulted from lower capital project accruals.

Including cash and cash equivalents, as well as the impact of foreign currency on the balance sheet, we had total working capital of $704.8 million at June 30, 2017 and $542.3 million at December 31, 2016. The current ratio was 3.43 to 1 at June 30, 2017 and 2.84 to 1 at December 31, 2016.

Cash Flows – Investing Activities

Cash used in investing activities was $87.2 million during the first six months of 2017 and included $85.2 million for capital expenditures. We expect that our total capital spending during 2017 will exceed the $143 million incurred in 2016, including anticipated spending on phase two of the new manufacturing facility in Singapore, and several improvements to our manufacturing and R&D infrastructure around the world. We expect to continue to finance capital spending through cash on hand and cash provided from operations, together with borrowing available under our $650 million revolving credit facility.

Cash Flows – Financing Activities

Cash provided from financing activities during the first six months of 2017 amounted to $77.5 million. The issuance of our 3.78% senior notes (see discussion below) resulted in an inflow of $250 million. We paid off $129.6 million on the revolving credit facility and paid dividends of $41.5 million. Our long-term debt of $628.0 million at June 30, 2017 increased $120.7 million since December 31, 2016, primarily due to the issuance of the 3.78% senior notes.

Debt

At June 30, 2017, in addition to the revolving credit facility and the 3.78% senior notes discussed below, we had outstanding senior notes in the aggregate principal amount of $350 million that bear interest at a fixed rate of 4.10% and are due in 2022. These senior notes are registered under the Securities Act.

On January 4, 2017, we issued $250 million in senior unsecured notes in a private placement with The Prudential Insurance Company of America and certain other purchasers. These notes bear interest at 3.78% and mature on January 4, 2029. Interest is payable semiannually and principal payments of $50 million are payable annually beginning on January 4, 2025. We have the right to make optional prepayments on the notes at any time, subject to certain limitations.

Revolving Credit Facility – At June 30, 2017, we had a $650 million revolving credit facility, with a $100 million sublimit for multicurrency borrowings, a $75 million sublimit for letters of credit, and a $20 million sublimit for swingline loans. The credit agreement includes an expansion feature, which allows us, subject to certain conditions, to request an increase to the aggregate amount of the revolving credit facility or obtain incremental term loans in an amount up to $150 million. In addition, provisions allow certain of our foreign subsidiaries to borrow under the agreement. Borrowings bear interest at variable rates. The revolving credit facility matures on October 28, 2019.

The unused portion of the revolving credit facility was $620.0 million at June 30, 2017 and $490.5 million at December 31, 2016. See Note 6 for additional information.

The 4.10% senior notes, 3.78% senior notes, and the revolving credit facility contain covenants, representations, and events of default that management considers typical of credit arrangements of this nature. The covenants under the 3.78% senior notes include negative covenants, certain financial covenants, and events of default which are substantially similar to the covenants and events of default in our revolving credit facility.

The more restrictive and significant financial covenants under the revolving credit facility include:

•A consolidated Leverage Ratio (as defined in the credit agreement) of no more than 3.50 to 1.00; and

•A consolidated Interest Coverage Ratio (as defined in the credit agreement) of no less than 3.00 to 1.00, calculated on a rolling four quarter basis.

20

At June 30, 2017, the Leverage Ratio was 1.59 and the Interest Coverage Ratio was 17.98 under the revolving credit facility, while at December 31, 2016 the Leverage Ratio was 1.28 and the Interest Coverage Ratio was 21.45. We were in compliance with all covenants under the revolving credit facility and the 4.10% senior notes at June 30, 2017 and December 31, 2016. We were in compliance with all covenants under the 3.78% senior notes at June 30, 2017.

As a percentage of total capitalization (total long-term debt and shareholders’ equity), our total long-term debt percentage increased from 51.2% at December 31, 2016 to 51.8% at June 30, 2017. The change in the percentage was primarily the result of the increase in long-term debt partially offset by the increase in shareholders' equity. The change in shareholders’ equity reflects our earnings and impact of the foreign currency translation adjustment offset by the impact of dividend payments. Normally, we repay any outstanding long-term debt with cash from operations or refinancing activities.

Critical Accounting Policies and Estimates

This Form 10-Q and our 2016 Annual Report include discussions of our accounting policies, as well as methods and estimates used in the preparation of our financial statements. We also provided a discussion of Critical Accounting Policies and Estimates in our 2016 Annual Report.

There have been no significant changes in our critical accounting policies and estimates from those reported in our 2016 Annual Report.

Recent Accounting Pronouncements

For a full discussion of the significant recent accounting pronouncements which may impact our financial statements, see Note 10.

Outlook

We are pleased with the overall performance of our business through the first six months of 2017. Our stated goal is to provide a 10% return per year for our shareholders over any five year period (defined by earnings per share growth plus dividends), although we may not necessarily achieve a 10% return each year. We continue to have confidence in our customer-focused strategy and approach to the market. We believe the fundamentals of how we run our business - a long-term view, safety-first culture, customer-focused solutions, technology-driven product offerings, and world-class supply chain capability - will continue to be beneficial for all of our stakeholders.

We expect our petroleum additives segment to deliver solid performance in 2017, after having posted strong operating results over the past several years. We expect that the petroleum additives industry shipment demand will grow at an average annual rate of 1% to 2% over the long-term, as there have been no significant changes in the positive fundamentals of the industry. Over the long-term, we plan to exceed the industry growth rate.

We have made significant investments to expand our capabilities around the world over the last few years, which are continuing in 2017. These investments have been and will continue to be in organizational talent, technology development and processes, and global infrastructure, consisting of technical centers, production capability, and geographic expansion. We intend to utilize these new capabilities to improve our ability to deliver the solutions that our customers value and to expand our global reach and improve profits. We will continue to invest in our capabilities to provide even better service, technology, and customer solutions.

On July 3, 2017, we completed our acquisition of Aditivos Mexicanos S.A. de C.V. which is a petroleum additives manufacturing, sales and distribution company based in Mexico City, Mexico. In addition, construction continues on phase two of our manufacturing facility in Singapore, which is expected to be completed in the second half of 2017 and will more than double our investment there.

Our business generates significant amounts of cash beyond what is necessary for the expansion and growth of our current offerings. We are making investments to position ourselves for the future. We regularly review our many internal opportunities to utilize this cash from a technological, geographic, and product line perspective. We believe our capital spending is creating the capability we need to grow and support our customers worldwide, and our research and development investments are positioning us well to provide added value to our customers. Our primary focus in the acquisition area remains on the petroleum additives industry. It is our view that this industry segment will provide the greatest opportunity for solid returns on our investments while minimizing risk. We remain focused on this strategy and will evaluate any future opportunities. Nonetheless, we are patient in this pursuit and intend to make the right acquisition when the opportunity arises. We will continue to evaluate all alternative uses of cash to enhance shareholder value, including stock repurchases and dividends.

ITEM 3.     Quantitative and Qualitative Disclosures About Market Risk

At June 30, 2017, there were no material changes in our market risk from the information provided in the 2016 Annual Report.

ITEM 4.     Controls and Procedures

Evaluation of Disclosure Controls and Procedures

We maintain a system of internal control over financial reporting to provide reasonable, but not absolute, assurance of the reliability of the financial records and the protection of assets. Our controls and procedures include written policies and procedures, careful selection and training of qualified personnel, and an internal audit program. We use third-party firms, separate from our independent registered public accounting firm, to assist with internal audit services.

We work closely with the business groups, operations personnel, and information technology to ensure transactions are recorded properly. Environmental and legal staff are consulted to determine the appropriateness of our environmental and legal liabilities for each reporting period. We regularly review the regulations and rule changes that affect our financial disclosures.

Our disclosure controls and procedures include signed representation letters from our regional officers, as well as senior management.

We have a Financial Disclosure Committee (the committee), which is made up of the president of Afton, the general counsel of NewMarket, and the controller of NewMarket. The committee makes representations with regard to the financial statements that, to the best of their knowledge, the statements do not contain any misstatement of a material fact or omit a material fact that is necessary to make the statements not misleading with respect to the periods covered by the report. They also represent that, to the best of their knowledge, the financial statements fairly present, in all material respects, our financial condition, results of operations, and cash flows as of and for the periods presented in the report.

Management personnel from our geographic regions also represent that, to the best of their knowledge, the financial statements and other financial information from their respective regions, which are included in our consolidated financial statements, fairly present, in all material respects, the financial condition and results of operations of their respective regions as of and for the periods presented in the report.

Pursuant to Rule 13a-15(b) under the Securities Exchange Act of 1934 (the Exchange Act), we carried out an evaluation, with the participation of our management, including our principal executive officer and our principal financial officer, of the effectiveness of our disclosure controls and procedures, as such term is defined in Rule 13a-15(e) under the Exchange Act, as of the end of the period covered by this report. Based upon that evaluation, our principal executive officer and our principal financial officer concluded that our disclosure controls and procedures are effective at the reasonable assurance level.

Changes in Internal Control over Financial Reporting

There has been no change in our internal control over financial reporting, as such term is defined in Rule 13a-15(f) under the Exchange Act, during the quarter ended June 30, 2017, that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

22

PART II – OTHER INFORMATION

ITEM 1.     Legal Proceedings

We are involved in legal proceedings that are incidental to our business and may include administrative or judicial actions. Some of these legal proceedings involve governmental authorities and relate to environmental matters. For further information, see “Environmental” in Note 7.

While it is not possible to predict or determine with certainty the outcome of any legal proceeding, we believe the outcome of any of these proceedings, or all of them combined, will not result in a material adverse effect on our consolidated results of operations, financial condition, or cash flows.

In late 2013, Afton initiated a voluntary self-audit of its compliance with certain sections of TSCA under the EPA’s Audit Policy. If any potential TSCA violations are discovered during the audit, we would voluntarily disclose them to the EPA under the Audit Policy. In August 2014, the EPA staff began its own TSCA inspection of both Afton and Ethyl. While it is not possible to predict or determine with certainty the outcome, we do not believe that any findings identified as a result of our audit or the EPA’s TSCA inspection will have a material adverse effect on our consolidated results of operations, financial condition, or cash flows.

Earnings Per Share [Abstract]

Earnings Per Share

Earnings Per Share

We had 23,670 shares of nonvested restricted stock at June 30, 2017 and 25,255 shares of nonvested restricted stock at June 30, 2016 that were excluded from the calculation of diluted earnings per share, as their effect on earnings per share would be anti-dilutive.

The nonvested restricted stock is considered a participating security since the restricted stock contains nonforfeitable rights to dividends. As such, we use the two-class method to compute basic and diluted earnings per share for all periods presented since this method yielded a more dilutive result than the treasury-stock method. The following table illustrates the earnings allocation method utilized in the calculation of basic and diluted earnings per share.

	$	627,976	$	507,275

The outstanding 4.10% senior notes have an aggregate principal amount of $350 million and are registered under the Securities Act of 1933, as amended (Securities Act).

On January 4, 2017, we issued $250 million in senior unsecured notes in a private placement with The Prudential Insurance Company of America and certain other purchasers. These notes bear interest at 3.78% and mature on January 4, 2029. Interest is payable semiannually and principal payments of $50 million are payable annually beginning on January 4, 2025. We have the right to make optional prepayments on the notes at any time, subject to certain limitations. The note purchase agreement contains representations, warranties, terms and conditions customary for transactions of this type. These include negative covenants, certain financial covenants, and events of default which are substantially similar to the covenants and events of default in our revolving credit facility. The proceeds from the 3.78% senior notes were used in part to pay off the outstanding amount on our revolving credit facility.

The capital lease obligation in the table above is related to the Singapore manufacturing facility.

The following table provides information related to the unused portion of our revolving credit facility:

(in thousands)	June 30, 2017		December 31, 2016
Maximum borrowing capacity under the revolving credit facility	$	650,000	$	650,000

Outstanding letters of credit	3,535		3,483
Unused portion of revolving credit facility	$	620,039	$	490,517

The average interest rate for borrowings under our revolving credit facility was 2.0% during the first six months of 2017 and 1.9% during the full year of 2016.

We were in compliance with all covenants under our debt agreements at June 30, 2017 and at December 31, 2016, as applicable.

Legal Matters

We are involved in legal proceedings that are incidental to our business and may include administrative or judicial actions. Some of these legal proceedings involve governmental authorities and relate to environmental matters. For further information, see Environmental below.

While it is not possible to predict or determine with certainty the outcome of any legal proceeding, we believe the outcome of any of these proceedings, or all of them combined, will not result in a material adverse effect on our consolidated results of operations, financial condition, or cash flows.

In late 2013, Afton Chemical Corporation (Afton) initiated a voluntary self-audit of its compliance with certain sections of the Toxic Substances Control Act (TSCA) under the Environmental Protection Agency's (EPA) audit policy (Audit Policy). If any potential TSCA violations are discovered during the audit, we would voluntarily disclose them to the EPA under the Audit Policy. In August 2014, the EPA staff began its own TSCA inspection of both Afton and Ethyl. While it is not possible to predict or determine with certainty the outcome, we do not believe that any findings identified as a result of our audit or the EPA’s TSCA inspection will have a material adverse effect on our consolidated results of operations, financial condition, or cash flows.

Environmental

We are involved in environmental proceedings and potential proceedings relating to soil and groundwater contamination, disposal of hazardous waste, and other environmental matters at several of our current or former facilities, or at third-party sites where we have been designated as a potentially responsible party (PRP). While we believe we are currently adequately accrued for known environmental issues, it is possible that unexpected future costs could have a significant impact on our financial position, results of operations, and cash flows. Our total accruals for environmental remediation, dismantling, and decontamination were approximately $15 million at June 30, 2017 and $16 million at December 31, 2016. Of the total accrual, the current portion is included in accrued expenses and the noncurrent portion is included in other noncurrent liabilities on the Condensed Consolidated Balance Sheets.

Our more significant environmental sites include a former TEL plant site in Louisiana (the Louisiana site) and a Houston, Texas plant site (the Texas site). Together, the amounts accrued on a discounted basis related to these sites represented approximately $9 million of the total accrual above at June 30, 2017 and $10 million of the total accrual above at December 31, 2016, using discount rates ranging from 4% to 9% for both periods. The aggregate undiscounted amount for these sites was $12 million at June 30, 2017 and $13 million at December 31, 2016. Of the total accrued for these two sites, the amount related to remediation of groundwater and soil for the Louisiana site was $4 million at both June 30, 2017 and December 31, 2016. The amount related to remediation of groundwater and soil for the Texas site was $5 million at both June 30, 2017 and December 31, 2016.

In 2000, the EPA named us as a PRP under Superfund law for the clean-up of soil and groundwater contamination at the five grouped disposal sites known as "Sauget Area 2 Sites" in Sauget, Illinois. Without admitting any fact, responsibility, fault, or liability in connection with this site, we are participating with other PRPs in site investigations and feasibility studies. In December 2013, the EPA issued its Record of Decision confirming its remedies for the selected Sauget Area 2 Sites. We have accrued our estimated proportional share of the remedial costs and expenses addressed in the Record of Decision. We do not believe there is any additional information available as a basis for revision of the liability that we have established at June 30, 2017. The amount accrued for this site is not material.

The fair value is categorized in Level 1 of the fair value hierarchy. No material events occurred during the six months ended June 30, 2017 requiring adjustment to the recognized balances of assets or liabilities which are recorded at fair value on a nonrecurring basis.

Long-term debt – We record the carrying amount of our long-term debt related to the 4.10% senior notes at historical cost, less deferred financing costs. We record the carrying amount of our long-term debt related to the 3.78% senior notes at historical cost. The estimated fair value of our long-term debt is shown in the table below and is based primarily on estimated current rates available to us for debt of the same remaining duration and adjusted for nonperformance risk and credit risk. The estimated fair value of our publicly-traded 4.10% senior notes included in long-term debt in the table below is also based on the last quoted price closest to June 30, 2017.

Recently Issued Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (FASB) issued ASU No. 2014-09, “Revenue from Contracts with Customers (Topic 606)” (ASU 2014-09). ASU 2014-09 replaces the previous guidance and clarifies the principles for revenue recognition. It requires a five-step process for revenue recognition that represents the transfer of goods or services to customers in an amount that reflects the consideration expected to be received by a company. ASU 2014-09 also requires enhanced disclosures regarding the nature, amount, timing, and uncertainty of revenues and cash flows from contracts with customers. ASU 2014-09 is effective for our reporting period beginning January 1, 2018. Entities can transition to the standard either retrospectively or as a cumulative-effect adjustment as of the date of adoption. We currently anticipate adopting the standard as a cumulative-effect adjustment. We expect to continue the evaluation, analysis, and documentation of our adoption of ASU 2014-09 (including those subsequently issued updates that clarify the provisions), throughout most of this year as we work towards implementation and finalize the impact the adoption will have on our consolidated financial statements.

In February 2016, the FASB issued ASU No. 2016-02, "Leases (Topic 842)" (ASU 2016-02). The FASB issued ASU 2016-02 to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and requiring disclosures related to certain information about leasing arrangements. Under the new guidance, operating leases are, in most cases, required to be recognized on the balance sheet as a lease asset and liability. A modified retrospective approach is required for the adoption of ASU 2016-02, which is effective for our reporting period beginning January 1, 2019. Early adoption is permitted. We are currently assessing the impact that the adoption of ASU 2016-02 will have on our consolidated financial statements.

In March 2017, the FASB issued ASU No. 2017-07, "Compensation-Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost" (ASU 2017-07), which requires that an employer report the service cost component of net benefit cost in the same line item as other compensation costs arising from services rendered by the pertinent employees during the period. The other components of net benefit cost are required to be presented in the income statement outside of operating profit. ASU 2017-07 also allows only the service cost component to be eligible for capitalization in assets. There will be no change to net income as a result of ASU 2017-07, which is effective for our reporting period beginning January 1, 2018. Retrospective application is required for the income statement presentation and prospective application is required for the capitalization of the service cost component in assets. The adoption of ASU 2017-07 will result in a change within operating profit with a corresponding change in other income (expense), net to reflect the impact of presenting all components of net benefit cost, except for service cost, outside of operating income. See Note 3 for the components of our net benefit costs. We do not expect a material impact to our consolidated balance sheets or consolidated statements of cash flows.

On July 3, 2017, Afton Chemical de Mexico, S.A. de C.V., an indirect, wholly-owned subsidiary of NewMarket Corporation, acquired approximately 99.5% of the outstanding capital stock of Aditivos Mexicanos, S.A. de C.V. (AMSA), a petroleum additives manufacturing, sales and distribution company based in Mexico City, Mexico.

We are performing a valuation of the acquired business, as well as finalizing the working capital statement and related final purchase price. We expect both to be completed during the third quarter of 2017, and we do not expect the purchase price to be significantly different from the $185 million cash paid.
